Abstract:
ABSTRACT This experiment was conducted to test the efficacy of Tageteserectaextract with bio-control agents, Trichidermahamatum and Paecilomyceslilacinus as individual treatments and in combinations on the growth of tomato plants and the development of root-knot nematode M. javanica. Inoculation of tomato plants with M. javanica(T1)resulted in significant suppression of the length and fresh weight of shoots and roots, when compared to uninoculated plants (T0 ). The means of mortality percent in J2 by fungal filtrates of P.lilacinus ,T. hamatum and T.erecta extract were 22.8 , 13.08 and 19.8% respectively. Application of the 2 biocontrol fungi and T. erecta (individually or in combination) significantly increased all tested growth parameters of tomato. Among individual treatments, the highest value of growth parameters, length of shoot, length of root, fresh weight of shoot and fresh weight of root were recorded in P.lilacinus treatment (T3) which were 18.07cm , 14.23cm, 21.56gm and 6.68gm respectively. In combination treatments, the maximum length of shoot (22.66 cm) and root (16.66cm) were recorded in T8(T. hamatum + P. lilacinus + plant extract ). From this study, it may be suggest that the improvement of plant growth is obtained in combination treatments than in individual treatments.
